含四齿O ^ N ^ C ^ N配体的稳健磷光铂(II)配合物:激基激发态及其在有机白光发光二极管中的应用
摘要:
明亮的白光:合成了由四齿O N C N配体支撑的,具有高发射量子产率(0.72-0.93)和高T d(> 400°C)的一系列高度坚固的铂(II)配合物。在配合物中,图中所示的配合物具有强的受激准分子发射,这归因于具有局部结构的单体三重态激发态。重点介绍了这种低带隙材料在单掺杂有机或聚合物白光发光二极管(WOLED)上的应用。

palladium(II) complexes with tetradentate O N C N ligands (see structure) exhibit intense green phosphorescence and long‐lived excited states with emission quantum yields and lifetimes up to 22 % and 122 μs, respectively. The complexes show potential as novel functional materials, with promising results in a variety of applications, such as oxygensensing, photocatalysis, and organiclight‐emitting diodes

Described are novel platinum (II) containing organometallic materials. These materials show green to orange emissions with high emission quantum efficiencies. Using the materials as emitting materials; pure green emitting organic light-emitting diodes can be fabricated. Since the novel platinum (II) containing organometallic materials are soluble in common solvents, solution process methods such as spin coating and printing can be used for device fabrication.
